What does ECU mean in MEDICAL

The Extensor Carpi Ulnaris (ECU) is an intrinsic muscle of the forearm that helps to extend the wrist. It originates from the medial epicondyle of humerus and inserts onto the base of the fifth metacarpal bone.

The ECU works with other muscles in its group, collectively known as extensors, to help extend the fingers and wrist. It also aids in pronation and supination of the forearm.

The ECU is located on the posterior side or backside of your forearm, below your elbow joint and above your hand. Its tendon can be felt by making a fist and squeezing your palm against a hard surface such as a table top.

To activate ECU, you must perform exercises such as dumbbell extensions, reverse curl extensions, towel curls and barbell curls that target this specific muscle group in order to strengthen them. In addition, stretching this muscle before workouts will ensure proper activation during exercise.

Yes, if strained or injured it can cause pain and decrease range of motion in one's wrist. If left untreated for a prolonged period of time it may lead to further injury or chronic pain issues in the area.
